I have a project using all 11 ADC Channels on the 16F886.

I note the external voltage reference channels/pins are shared with the ADC channels AN2 & AN3 :?

Anyway round this? I can't disconnect the device the adc is measuring from the adc pins AN2,AN3.

I'm fairly happy with the VDD/VSS reference method but was just thinking about using something with more precision than the power supply.
